<p> As part of the migration of Eclipse Platform to Batik <code>1.9.0</code>, the third-party Apache Batik bundles changed in the following way:
<ol>
	<li>Bundle <code>org.apache.batik.css</code> was bumped to version <code>1.9.0</code>. </li>
	<li>Bundle <code>org.apache.batik.util</code> was bumped to version <code>1.9.0</code>. </li>
	<li>Bundle <code>org.apache.batik.util.gui</code> version <code>1.8.0</code> was removed. It was a dependency of version 1.8.0 of <code>org.apache.batik.util.gui</code> bundle but it is no longer a dependency of version 1.9.0. </li>
	<li>Bundle <code>org.apache.batik.i18n</code> version <code>1.9.0</code> was added as it was needed by bundle <code>org.apache.batik.css</code>. </li>
</ol>
</p>

<h2><a name="lucene">2. Apache Lucene bundle changes</a></h2>
<p> As part of the migration to Lucene 7.1, the third-party Lucene bundles were updated from version 6.1 to 7.1.
<ol>
	<li>Bundle <code>org.apache.lucene.core</code> was bumped in version so consumers should not see any difference except the changes of Lucene itself (see link below).
	</li>

	<li>Bundle <code>org.apache.lucene.misc</code> was removed as it is no longer used by Eclipse Help system.
	</li>
</ol>

See <a href="https://lucene.apache.org/core/7_1_0/changes/Changes.html">
Lucene Change Log</a> for details on how the Apache Lucene changed between these versions.
